To all whom it may concern:

Be itknown that I, CARL A. .HANsoN, a

punch,

, citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Saw Sets, of

which the following is a specification] The present invention relates to'an improved saw set and has for its object to provide a very simple device of this character by means of which the teethof a crossa cut saw can be very quickly andeasily set. A further object resides; inithe provision of a saw setting devicewhich may bearranged upon saw blades of conventional construction and is of such construction that the device may be readily moved upon the blades for the engagement ot the settingmembers with the successive teeth of the saw. v

A still further object of the invention is to generally improve upon a sawset ofthis character by providing a device which will be extremely simple and efficient in con struction, reli able in operation, comparative ly inexpensive to manufactureand well adapted to the purpose forwhich it is designed. i i

Vith these and otheryobjects in vieugthe invention consists of the novel featuresof construction, combination andtarrangement of parts hereinafter fully described and,

claimed, andillustrated in the 111g drawmgs, 1n \Vl11C l1- Figure 1 is a side elevationofa saw set accompanyconstructed in accordance withthe present invention showing the same arranged upon a saw blade, I a Figure 2 is an end elevation thereof, a V Figure 3 is-asection t-therethrough, A Figure 4 is a detailed perspectiveofithe main block, I I

The hinged block shown inFigures 6 and 7 and indicated generally at 12 is constructed with the saw tooth receiving recess 13; which communicates with. a bore 14- adapted to, receive the punch 15. This punch 15 is preterably constructed with an arrow head 16 mounted on the endiotthe shank'17; On this shank 17 between the ends ithereof is a piston member 18 ridable in the bore 14.

A plate 19 is adapted'to bcfixed onthe end of the block 12 sothat its "rectangular shaped opening 20 registers with the boreil for re 'ceiving the end of the shank 17 so that the same may extendtherethrough. The block 22 'shown in Figure 8 is similarly" constructed to the block 12 exceptthat:tworecesses '13 are provided withcorrespondingbores 14' and the plate19 isprovided witha pair of rectangular openings 2O so that .two punches 15 may be reccivedgi' The hinged 101001123 shown in Figure, 10 i provided with thetoot-h receiving recess 13 andregisterin'g bores 14s and alse, vvithga"longituolin ally extending groove Zt upon its end for the purpose of receiving thecross piecef25 supporting the two punches 26 adaptedto place by a set screw 42.

slide in the bores 14. A plate 27 is suitably mounted over the end of the block havingthe groove 24 therein so that its rectangular shaped opening28 receives the shank 29 projecting from the cross piece 25 sup porting the punches 26. Each of the blocks 12, 22 and 23 are provided with a pair of extensions 30 terminating in the rolled cars 31 adapted to be received in the recess 2 of the main block 1 so that the bolt 32 may pass therethrough and through'the openings 2 thereby hinging these hinged blocks in relation to the main block 1 as will be readily understood from an inspection of Figure 3.

In Figures 14 and 15 I have illustrated a slightly modified form of the main block 1 which is provided with the usual recess 2 and openings 3. This block, however, is provided on its rear face with the projecting threaded studs 35 which are adapted to extend through the slots 36 in the offset lips 37 of the brackets 38 which are of angular construction including the normally vertical arm 39 and normally. horizontal arm 40. This normally horizontal arm 40 terminates in a U-shaped clamp 41 for engaging the edge of the saw blade as is shown in Figures 14 and 13 and is held in This allows the block tobe shifted longitudinally in relation' to the saw without the necessity of moving the brackets and also allows the brackets tobe set in relation to the saw whereby a device may be used with saws wherein the teeth are not evenly spaced in relation to each other.

In Figure 16 .I have shown a modified form of the bracket which includes the vertical arm 39 and horizontal arm 40 and also the offset lip 37 having a slot 36 therein. An auxiliary leaf 43 is pivoted on the hori zontal arm 40 as at 44 and is provided at its terminal with a depending lip 45. A set screw 46 carried by the leaf 43, bears upon the arm 40, turning of the screw producing an adjustment of the leaf.

T It is thought that the operation and construction of the invention will now be clearly understood without a more detailed description thereof. It is, however, desired to point out that numerous changes in construction and in the combination and ar-- rangement of parts may be resorted to with out departing from the scope of the inven'- tion as hereinafter claimed.
